Answer 1

Answer:

hlo

your answer is here !

Step-by-step explanation:

Let us first find the fraction of green, blue and yellow balls

1/4 + 1/8 + 1/12 = 6 / 24 + 3 / 24 + 2 / 24 , common denominator

= 11 / 24 , add numerators

The fraction of white balls is given by

24 / 24 - 11 / 24 = 13 / 24

So the fraction 13 / 24 corresponds to 26 balls. If x is the total number of balls then

(13 / 24) of x = 26 balls

or (13 / 24) × x = 26

x = 26 × (24 / 13) = 48 ,

total number of balls

The fraction of blue balls is 1 / 8 of x.

The number of blue balls is given by

(1 / 8) of 48 = 6 balls.

Answer 2

Step-by-step explanation:

There are 4 colours of balls - green, blue, yellow and white.

Add (1/4)+(1/8)+(1/12) = (6/24)+(3/24)+(2/24) = 11/24 so the balance or (24–11)/24 = 13/24 = 26 white. Hence the total number of balls are 2*24 = 48.

Of the 48 balls, green are (1/4)*48 = 12, blue are (1/8)*48 = 6, yellow are (1/12)*48 = 4 and the rest, white are 26.

Check: Total number of balls = 12+6+4+26 = 48

Answer: 6 balls are blue.
